STAGE MOUNTING FOR GINEMATOGRAPHIG PICTURES Application filed March 22,1928. Serial No. 263,718.

My invention relates to the stage mounting for cinematographic or motionpictures and has a particular reference to the arrangement of a movablestage.

a The object of m invention is to provide an arrangement wlierebydifierent portions of the stage for taking motion pictures can be movedat a difi'erent rate of speed, one of these portions containing also thecamera for w taking pictures. This arrangement can be used to producespecial effects by uncovering gradually or suddenly difierent portionsof the stage setting so as to create an impres sion with the observerofthe pictures, of a 15 more intimate and personal contact with thescenery and action on the stage.

The further object of my invention is to provide a stage which can bemoved in steps,

rhythmically and in synchronism with a certam music. This arrangementmay be especially useful in taking pictures of dancing artists or groupsof artists.

My invention is more fully described in the accompanying specificationand drawing 25 in which Fig. 1 is a sectional elevation or" my stagearrangement, Fig. 2 is a plan view of same, and Fig. 3 1s a diagrammatlcviewoi electricalv connections.

to My stage arrangement consists of a central round stage 1 mounted on atube 2 which is supported on a ball bearing 3 on a central pillar 4:.The tube 2 is guided in its lower portion by means of bearings 5 and ispro 135 vided with a gear wheel 6 in mesh with a worm '2 on the shaft ofan electric motor 8. lit is understood of course that any other suitabledrive or transmission may be employed to rotate the stage 1- ori thecentral pillar or post 4:. V ,7

The central stage 1 is surrounded with a circular or ring stage 9supported, with braces 10 on a tube 11. This tube rests on a hearing 12is separated from the tube worm gear 15 in mesh with a worm 16 on theshaft an electric motor 17.

The motor 17 and the hearings 12 are mounted on a raised platform 18.-The ring stage 9 is placed in a circular aperture in. the

floor 19 of the motion picture studio. This is not necessary, however,and it may operate independently if provided with safety railings on theoutside of the ring 9.

The studio floor may be made of a soundproof material it it is intendedto make Vitaphone pictures, or pictures combined with vocal efiect.

A camera in a sound-proof cage 20 is mounted on the stage 9, alsoflood-lights 21. @n the opposite side of the stage difierent settings 22are placed, scenery, furnitureetc.

A controller 23 is placed on the stage 9 near the cage 20. Thiscontroller is connected electrically with a source of electric power andwith motors 8 and 17 by means of contact rings 24: on the tube 11.

The operation of my arrangement is as follows.

Dancers are placed on the central stage P 1 which is set in a slowrotary movement. A director can control this movement by 'means ofcontroller 23, may stop it entirely or reverse. With this arrangement itbecomes possible with a single camera to take pictures from difierent anles, also to obtain a more strikingand vivid e ect by following thedancers movements and presenting them always from the most advantageouspoint of view. This arrangement eliminates the necessity to use severalcameras at one time, patching together the films afterwards with a greatWaste of the unused films.

Other special eitects may be obtained with my arrangement, for instance,the play of a. mother with a child viewed from difierent angles, theentrance of the hero into new surroundings, roundings to the observersview before the hero" himself appears. I

A more rapid relative movement may he obtained by rotating the twostages in different directions, and it may be slowed down by rotating inthe same direction with difierent velocities.

For taking pictures of dancers performing rhythmical movements of waltz,two step and similar dances, it is important that the movement of thestage should he also inter-- mittently rhythmical, in order toaccentuate by quickly opening these sur- 4 r Z the effect of the danceon the observers. Itds also desirable that the rhythmical movement ofthe stage should be periodically in synchronism with the movement of theshutter in the camera. For this purpose I use synchronous motors 8 and17 rotating in syn-1 chronism with a motor 25 which operates a shutterby means of some well known intermittent mechanism 26. These motors canbe controlled by a controller 28 the current for which is supplied bywires'27 through a system of contact rings similar to rings 24:. Themotor 8 (the other motor is not shown on the a diagrammatic drawing Fi3) operates the stage 1 through a chain 0 gears 28 and by means of anintermittently rotating mechanism 29. J 1

Important advantages of my arrangement are that it provides means forobtaining new effects in the art of making motion pictures,

by changing scenery either gradually, or more or less quickly, also bypermitting continuous exposure of moving objects from the mostadvantageous points ofvieW, eliminating the necessity of employingseveral cameras at one time.

I claim as my invention:

In a stage mounting for cinematographic pictures, the combination with acircular stage for artists, of a rotative mounting for said stage, aring-shaped stage surrounding said circular stage, a rotativemountingfor.

said stage, means to independently rotate said stages, means to ,controlsaid rotation, said means being located on said ring-shaped stage, andacinematographic camera on said ring-shaped stage, said ring-shaped stagebeing adapted to support scenery opposite said camera.
